The LEDs you are most likely to use are the through hole LEDs with two legs.

Unlike some chips that have dozens of pins with names and special uses, LEDs have only two wires. One wire is the anode (positive) and another is the cathode (negative).

It used to be that LEDs were only red or maybe yellow and orange. Which is why early electronics from the 70s and 80s only had red LEDs. The color emitted from an LED has to do with what type of material they are made of. So red, for example, is made with Gallium Arsenide.\u003c\/p\u003e\n\u003cp style=\"margin-top: 0px; margin-bottom: 0px; padding: 10px 0px 0px;\"\u003eWhen we first started making electronics in the late 90's.
